The acute toxicity and effects of diazinon on some haematological parameters kutum (Rutilus frisii kutum, Kamensky, 1901) weighing 613.33 ± 157.06 g were studied under static water quality conditions at 15 °C 2 oC. These experiments carried out based the standard TRC, 1984 method over 4 days, controlled for effective physicochemical factors having pH rangesof 7-8.2, total hardness 300 mgl -1 (caco3), dissolved oxygen 7 . results showed that 96h LC50 value was 0.4 maximum allowable...

In this study, we examined the age-dependent changes of sperm quality parameters and female properties in common carp. As well as, reproductive performance brooders was tested using two age groups male (i.e. 2 3 years old brooders). For aim, were crossed randomly from classes. There significant differences density percentage motile spermatozoa between ages, but duration motility spermatocrit did not differ groups. Some seminal plasma composition such as pH, chloride, acid phosphatase (ACP)...

In this study, changes of pH, ionic (Na+, K+, Ca2+,and Mg2+), biochemical (total protein, glucose, and cholesterol)compositions seminal plasma, sperm motility traits (percentage motile spermatozoa movement duration), production characteristics (sperm volume, spermatocrit, density) were studied in Caspian roach, Rutilus rutilus caspicus, during spawning migration. Sperm 10 males was collected three times the migration (in February, March, April). The results showed that parameters duration)...

Abstract The aim of this study was to assess the changes in hematological and plasma indices Ctenopharyngodon idella (Val.) with regard age, sex, hormonal treatment. Sixty specimens C. idella, comprising fifteen each age (6, 12, 24, 36 months) were used evaluate factor. Additionally, 20 fish, both females males, designated determine blood sex following biochemical indexes determined plasma: glucose, cholesterol, triglycerides, total protein (TP). Glucose triglyceride levels differed...

A polyculture system composed of western white shrimp, Litopenaeus vannamei and Mullet, Mugil cephalus, was established to create favourable biological condition improve shrimp growth. Totally, nine earthen ponds 600 m2 (three treatments with three replicates) were prepared in the Gwadar area (located coastal Oman Sea, southeast Iran) for our experiment. The L. post-larvae (PLs) (average body weight: 0.007 ± 0.001 g) stocked at a density 20 PLs m−2 each experimental pond. After 40 days...

This study was carried out to investigate the effects of probiotics and Fe ion on growth survival rainbow trout, Oncorhynchus mykiss frys. For this purpose, frys were fed with dry pellets containing various ratios for a period 30 days after absorption alevins' yolk sac. The parameters measured every 6 days. According results, values feed conversion ratio in lowest fish by only probiotic [i.e. at rates 1% (T1) 0.75% (T2) pellet weight]. In contrast, weight gain percent specific rate...

The main aim of this study was to examine the effects a polyculture system on control external parasites western white shrimp, Litopenaeus vannamei. To end, shrimp postlarvae (PLs) were stocked in nine earthen ponds (600 m2) at density 20 PLs m−2 and reared for 4 months. After 40 days stocking, Mullets, Mugil cephalus, various densities including: (0 fish/100 m2 pond), treatment 1 (T1: 2 pond) (T2: pond). Over course experiment, shrimps investigated by preparation wet mount from gill tissue....

We examined the effects of different dietary levels ascorbic acid (vitamin C) and αtocopherol E) their combinations on growth, survival; some haematological immunological parameters Caspian brown trout, Salmo trutta caspius juveniles.The experiment was designed as 15 experimental treatments one control group.480 fish (35±5.5 g) were fed by diets containing Vit C E diet separately for a period 2 months.According to results, improved survival growth including specific rate (SGR), percent...
